The Screening Type Chain Bucket Dredger is a multi-functional equipment specially designed for integrated dredging and screening operations. It adopts a core structure of chain bucket digging and built-in screening net linkage, driven by energy-saving diesel power to rotate the chain bucket to dig materials, complete graded screening synchronously, and then transport them to the designated area for unloading through the chain. It realizes the integrated and coherent operation of dredging, screening, conveying and unloading. The equipment has the advantages of firm structure, wear resistance, energy saving, intelligent control, strong adaptability and accurate screening. No additional screening equipment is needed, which greatly saves costs. It can be adapted to many scenarios such as placer gold mining, river sand mining and dredging. It can not only improve operation efficiency, but also increase the recovery rate of placer gold and sandstone. It is a cost-effective core first choice for small and medium-sized dredging and screening operations.

Product Advantages & Technical Highlights
Integrated Screening: Dredging, screening and conveying are completed synchronously, eliminating the secondary sorting process.
Strong Adaptability: Strong chain bucket digging force, capable of dredging sludge, clay, sand, gravel and sundries.
Energy Saving & Environmental Protection: Separate waste soil and usable materials while dredging, reducing outward transportation volume.
High Operation Efficiency: Continuous cycle operation, higher efficiency than ordinary chain buckets and manual sorting.
Wide Working Conditions: Constructible in rivers, ponds, reservoirs and water areas with many impurities.
Low Failure Rate: Mature structure, smooth screening, not easy to block, durable in use.
Applicable Scenarios & Materials
Applicable Scenarios
Urban inland river dredging, medium river channel dredging, reservoir dredging
Fish pond and shrimp pond renovation, sand-rich river channels
River channels with construction waste deposition, landscape lake dredging and screening
Applicable Materials
Sludge, silty clay, old sludge, fine sand, medium and coarse sand, gravel-containing sediment
